Information on the physiological state of plant canopies of crops during the growing season is essential for growers in decision-making such as foliar N and plant growth regulator applications for maximum yield. The aim of the study was to determine optimal vegetation indices for discriminating among four winter spelt and wheat varieties cultivated at six different organic and inorganic N fertilizer treatments. The suitability of the vegetation indices to predict yield was investigated as well. The results showed that the MCARI (Modified Chlorophyll Absorption Reflectance Index) was found to be the best for discriminating among spelt and wheat varieties and the most spectrally distinctive spelt variety was Schwabencorn. Among the tested indices, NDVI (Normalized Difference Vegetation Index) and MCARI could be used to most clearly distinguish the N treatments. A relatively high correlation occurred between the vegetation indices and grain yield of spelt and wheat. This relationship is stronger if the spectral data from different measurement dates are taken into consideration. Therefore, the best yield predictions (R2 = 0.79) were obtained using the cumulative SR index.
